iron ore processing for blast furnace

How it works The Blast Furnace Stoke on TrentBlast furnace Facts for Kids Kiddle encyclopedia

This iron rich ore can be charged directly into a blast furnace without any further processing Iron ore that contains a lower iron content must be processed or beneficiated to increase its iron content Pellets are produced from this lower iron content ore This ore is crushed and ground into a powder so the waste material called gangue can be removed The remaining iron rich powder is rolled A blast furnace is a special type of furnace They are used to make iron from ore Blast furnaces are very large They can be up to 60 metres 200 ft tall and 15 metres 49 ft in diameter

Use of Iron Ore Pellets in Blast Furnace Burden Plastics convert iron ore to steel Feedstock recycling in

Use of Iron Ore Pellets in Blast Furnace Burden Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 8 20 mm in diameter Hot metal from the blast furnace process is the beginning of this cycle Plastic materials rank among the second most important basic materials with an annual global production of about 260 million tonn Today a modern and sustainable technology can combine plastics recovery at its end or life with the production of steel As one of the most demanded and fi nite natural resources in the
